Re arranging track order in wavlab album

Why don’t track names move any more when you re arrange track order in album.
The clips move but names and numbering stay the same.

Not sure what you are speaking about. An album is made of clip sets calles “Titles”. Not tracks.
And clips are not automatically numbered, nor are markers that define Album titles.

In Wavlab 10, if I were mastering a CD I could import, say 12 tracks and then put them in the order I wanted by moving them up and down in the album window. In wavlab 10 the titles I had moved would also move so it was easy to check the running order was correct. Now in 12 the clips move but the titles in the album window don’t.

I don’t think there is a difference between WaveLab 10 and WaveLab 12. You must mistaken. If you want to rearrange the title order, you don’t have to rearrange clips, you have to rearrange the titles in the album window. In view of the last sentence of your last message, it is not what you do.
